It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values set forth in these examples do not limit the scope of the invention unless otherwise specifically stated.

The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application or uses.

In all examples shown and discussed herein, any specific values are to be construed as illustrative only and not as limiting. Accordingly, other examples of the exemplary embodiments may have different values.

The invention discloses a flexible connection structure of a connector, as shown in Figures 1-4.

It includes a connector body 1, a flexible conductor 4 and a transmission conductor 5. The connector body 1 is provided with a plug terminal 2. The end of the plug terminal 2 is provided with a first connector 3. The end of the transmission conductor 5 is The second connecting piece 6 is provided at the bottom;

One end of the flexible conductor 4 is electrically connected to the first connecting member 3 , and the other end is electrically connected to the second connecting member 6 .

In existing connector structures, the transmission conductor 5 is directly connected to the terminals in the connector body 1 . The entire connection structure makes the connector and terminals rigidly fixed, and the terminals will be eccentrically worn during the plugging and unplugging process of the charging gun. The phenomenon of eccentric wear refers to the repeated friction between the terminal and the mating end due to uneven force in all directions, resulting in damage to the coating and exposure of the terminal body. After the terminal body is exposed, the resistance increases, the current weakens, and the heat generation increases, which affects the safety and charging efficiency of high-voltage charging in the long term. The flexible conductor 4 of the present invention can not only conduct electricity, but also enable the plug terminal 2 in the connector body 1 to have a certain movable space through its own flexibility. When the charging gun is inserted into the connector body 1, the plug terminal 2 will move slightly in the direction of the insertion force of the charging gun due to the presence of the flexible conductor 4, thereby avoiding excessive force on a certain surface caused by rigid contact. The friction strength increases. In addition, the soft nature of the flexible conductor 4 makes it unsuitable for easily disassembled connection methods such as screwing, and can only be fixed connection methods such as welding, which makes it difficult to separate it from the transmission conductor 5 for easy replacement. In this case, disassembly can be facilitated by providing the second connecting member 6 to connect the flexible conductor 4 and the transmission conductor 5. That is, when the connector body 1 needs to be replaced, the second connecting member 6 and the transmission conductor 5 only need to be separated.

Furthermore, when the second connecting member 6 vibrates, the flexible conductor 4 deforms to buffer the vibration of the second connecting member 6 . When the vehicle is traveling, the transmission conductor 5 will swing along with the vehicle body. Long-term swinging will cause the second connector 6 to vibrate. When the second connector 6 vibrates, it will drive the plug terminal 2 in the rigid connection. Shaking, long-term shaking will damage the connection structure of the plug terminal 2 and the connector body 1. Therefore, the flexible conductor 4 can prevent the vibration of the second connector 6 from being transmitted to the plug terminal 2 through its own deformation, thereby protecting the plug terminal. 2.

In some embodiments, the flexible conductor 4 starts from the end connected to the second connector 6 and along the length direction of the flexible conductor 4, a portion accounting for at least 2% of the length of the flexible conductor 4 undergoes radial displacement. . If the length of the radial displacement of the flexible conductor 4 is too small, the vibration buffering is not enough, and the vibration of the second connecting member 6 cannot be fully buffered. In order to find a suitable ratio of the radial displacement of the flexible conductor 4 to the length of the flexible conductor 4, The inventor has conducted relevant tests. The test method is to select the same second connector 6 and different flexible conductors 4 to form a sample. The flexible conductors 4 have different lengths capable of radial displacement. Conduct a vibration test on the sample for one hour. If the impedance increase rate is greater than 2%, it is unqualified, indicating that fretting corrosion still exists, and it is unqualified. The results are shown in Table 1.

Table 1: The impact of the ratio of the radial displacement length of the flexible conductor 4 to the length of the flexible conductor on the impedance

As shown in Table 1, when the ratio of the radial displacement of the flexible conductor 4 to the length of the flexible conductor is less than 2%, the impedance between the flexible conductor 4 and the second connector 6 increases by more than 2% after the vibration test. Therefore, The inventor preferably prefers that a portion of the flexible conductor 4 that accounts for at least 2% of the length of the flexible conductor 4 undergoes radial displacement along the length direction of the flexible conductor 4 starting from the end connected to the second connector 6 .

Therefore, the inventor found through testing that if the vibrating part of the flexible conductor 4 is less than 2% of the total length of the flexible conductor 4, it cannot effectively buffer the vibration of the second connector 6, and the force generated by the vibration is concentrated and released on the flexible conductor 4 If the connection point with the second connecting member 6 is left this way for a long time, it will easily cause the two to separate and cause an open circuit. Therefore, the inventor prefers that at least 2% of the length of the flexible conductor 4 undergo radial displacement.

In some embodiments, the flexible conductor 4 starts from the end connected to the first connector 3 and along the length direction of the flexible conductor 4, at least 1% of the length of the flexible conductor 4 does not occur in the radial direction. Displacement.

If the part of the flexible conductor 4 that does not undergo radial displacement is too small, the vibration of the second connector 6 will still be transmitted to the first connector 3. In order to find a suitable flexible conductor 4 that does not undergo radial displacement, the length of the flexible conductor 4 accounts for For example, the inventor conducted relevant tests. The test method was to select the same first connector 3 and different flexible conductors 4 to form a sample. The flexible conductors 4 have different lengths capable of radial displacement. Conduct a vibration test on the sample for one hour. If the impedance increase rate is greater than 2%, it is unqualified, indicating that fretting corrosion still exists, and it is unqualified. The results are shown in Table 2.

Table 2: Effect of the ratio of the length of the flexible conductor 4 that does not undergo radial displacement to the length of the flexible conductor on impedance

As shown in Table 2, when the length of the flexible conductor 4 that does not undergo radial displacement accounts for less than 1% of the length of the flexible conductor, the impedance between the flexible conductor 4 and the first connector 3 after the vibration test increases by more than 2%, which is Unqualified. Therefore, the inventor prefers that the portion of the flexible conductor 4 that accounts for at least 1% of the length of the flexible conductor 4 does not undergo radial displacement along the length direction of the flexible conductor 4 starting from the end connected to the first connector 3 .
